DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, this system of the present invention comprises a number of color light tubes 101 and a numerical control device 102 for controlling the color light tubes 101. Thereof, using with combination of said tubes 101 or single tube 101 is allowable, each tube of which is controlled by the numerical control device 102 with whose color, intensity and duration of light emitting. The numerical control device 102 comprises a microprocessor or a timing sequential circuit, its main function is to generate different driving signals in combination and to apply them to respective color light tubes on the basis of demands.

In embodiment of the invention shown as FIG. 2, as the illuminating unit, color light tube 201 inside contains three neon lights which produce red, green and blue of tricolor, each neon light of which can be controlled respectively. Electronic transformer 202 can be connected between the neon lights and the numerical control device for decreasing output power of the numerical control device. Said numerical control device control three tricolor neon lights through the electronic transformer 202 or drive them directly. In other words, numerical control device 203 drives each neon light of color light tube through electronic transformer 202 according to preset programs at any period of time, and controls the intensity of every neon light at any time circularly.

The processes for driving and controlling light source has the following steps: 1) select or setup illuminating programs in numerical control device 203; 2) fetch and form the corresponding data on the basis of program selected; 3) transform the intensity digital data into analog signal; 4) magnify the analog signal; 5) numerical control device 203 send the magnified signals to electronic transformer 202; 6) electronic transformer 202 send the driving signals to three glowers of every tube to produce corresponding colorful light.

The system according to the present invention can produce multi-color light in one color light tube by method of physical blending. Shown as FIGS. 3-6, three parallel tubes 1 of red, green and blue are fixed in arrangement of equilateral triangle in light-blending cover 2, each of light tube 1 is neon light and light-blending cover 2 is ivory-white glass tube coated with fluorescence powder inside, both ends of the light tube are provided with pins 3 of glowers. Because space among every neon light and the light-blending tube is retained, diffraction will occur, this can make light of different colors blended, result in that generated light will be more soft and comfortable.

Controlling the light of the said neon light at any time manually or automatically can produce main light of red, blue, yellow, green, pink, black and ivory-white and other middle-color light. For example, blue light will be produced if the blue neon light is lighted; red light will be produced if the red neon light is lighted; green light will be produced if the green neon light is lighted; if red and blue neon lights are lighted together, pink light will be produced. If green and blue neon lights are lighted together, black light will be produced; if red, blue and green neon lights are lighted together, white light will be produced. Different effect will occur if proportion of two or three of the light intensity is controlled differently.

For better effect, another light-bending layer can be inserted between tricolor tube 1 and light-blending tube 2.

The said light-emitting bodies can be used of LED (Light Emitting Diode) or its crystal chip to generating red, green and blue light, which the pins of LED can be spread from one side.

In the embodiment of the present invention shown as FIG. 7, the numerical control device includes signal generator 701, counter 702, program setup unit 703, data storage unit 704, DIA converting unit 705, power magnifying unit 706 and load unit 707. Here the load unit 707 can be electronic transformer or LED, or light source of tricolor neon lights. Among which, signal generator 701 used to obtain pulse signal from main power and send them to counter 702, and then provide DC to every unit. Counter 702 is used to produces timing sequential signal for controlling whole illuminating process. Program setup unit 703 has following function means: 1) setup of time to start and stop; 2) setup of color; 3) setup of intensity. For example, the program setup unit 703 can be lighting mode setting switch, or an interface which can receive local or distant lighting program instruction. Data storage unit 704 will memorize lighting data formed by program setup unit 703, including corresponding preset program for tricolor tube. For example, each of tricolor can be expressed with four bits, red, green and blue color can be expressed with binary system respectively, for instance, green color as (0,1,0); red color as (1,0,0); blue color as (0,0,1); red and blue color as (1,1,0). If intensity is different, it can be expressed as (4,9,0), and so on. D/A converting unit 705 can transform data provided by data memory unit 704 into analog signal, power-magnifying unit 706 will magnify the analog signal provided by D/A transformation unit 705 and then sent to load unit 707.

Besides intensity of color, other aspects under control includes duration and sequence. For example, there are different program and data for intensity circulation in single color and for multi-color circulation.
